摘要：

A commercial 1‐butene LLDPE, Stamylex 1048, is cross fractionated by dynamic direct extraction and subsequent solution crystallization. The fractions are characterized by determining molecular masses Mn, Mn, and Mw and the comonomer content. DTA measurements are performed on unannealed and annealed samples of the fractions. The temperatures and specific heats of crystallization and fusion can be interpreted by reflecting the influence of molecular weight and comonomer content. The presented results are compared to data of 1‐butene LLDPE published in the recent literature. Copyright © 1990 John Wiley & Sons, Inc.
